model	The transition-model output of the function step3().
deltaT	The interval for which the transition probabilities should be calculated.
initialCovariateScores	The covariate scores for which the probabilities should be calculated. The default is NULL, which implies that any scores are set equal to the sample means.
transitionCovariateScores	The covariate scores for which the probabilities should be calculated. The default is NULL, which implies that any scores are set equal to the sample means.
rounding	The number of decimals to which the results should be rounded. The default is 2.
